Honestly the coolest gadget I've ever owned! I saw ONE Instagram advert and I was sold 👏🏽 I've never been that easy to "influence" but I was figuratively ready to launch my money at it! 😂 And god was it worth it 🙏🏼 It's made loading for hip thrusts and deadlifts so much easier and I don't know how I survived so long without one 🤷🏽‍♀️

Great Customer Service

I don't typically write reviews, but the customer support attached to Karta is next to none! The support staff were friendly, replied in a timely matter, understanding, and most of all extremely helpful. A great, high quality product backed by great, high quality support

PR on deadlift after using this!!

Obsessed with this water bottle!!! I have a pretty big collection of water bottles but this is my new gym necessity! Got a 300lbs PR on deadlift since I wasn't straining my back to get the weights on throughout my lift! If you're second guessing if this is real, just know this is my first review I have ever written on a product and I will keep bragging about it to everyone I know who lifts often!

Hey Kristi, thanks so much for your review and congrats on your PR!!! We had thought the bottle would help people save energy in the setup and not engage the lower back as much as changing weights without it so it's great to hear that it's worked out! - Pete

This thing is awesome

This thing is awesome. Absolutely love it. I get asked about it every time I'm doing deadlifts. It's like being the kid at recess with the cool toy everyone wants to play with. I've loaded 425 with it and it handled it fine. Looking forward to 5 plates.

Awesome!!

I ordered this bottle last year before Christmas and there way a delay because of supply chain issues. They kept in know of everything and refunded me. They also contacted me when they came back into stock and I ordered it again and received it within 3 or 4 days. Awesome bottle, use it almost everyday.. does need a handle but will manage with an Amazon one.

Bigger and better than you think it will be…

I saw this advertised on Instagram and thought, yay finally something practical that I actually need. I find it hard getting the plates on and off a bar but this bottle really does help. It’s surprisingly sturdy, has a rubber base so doesn’t slip and holds a good amount of water, my PT even commented when he saw it and was quite impressed. One of the best gym items I’ve ever bought. Def recommend.

Worth the wait

I preordered the bottle at the end of 2022, the delivery date was pushed back a couple of times and as disappointing that was the first time I used it once it arrived I knew straight away it was totally worth the wait (think I maybe just got unlucky with supplier timing for my order, I believe they're in stock atm) The bottle is definitely sturdy, little bit wobbly when it's not completely full but I just steady the end of the barbell with my shin & have never had any issues! The everyday lid is also great for general use,absolutely would recommend all of the products to any lifter 💪😍

Good product and communication

The Karta bottle was such a reach for me. I figured I’d try it, but I didn’t know if I’d actually like it or if it was too good to be true. I tested it under about 200lbs of weight and it had no issues. I know it can support way more, but I’m not there yet, so I didn’t test it to that extent. The communication with the company is great, too. They informed me that the strap for the bottle would be available for free, considering mine didn’t come with one, and that I’d only have to pay for shipping.

The only reason why I removed a star is due to the slight balancing struggle of the bottle under a bar when putting on weight. It’s not super steady but, at least in my case, it never actually fell. It just wobbles.

Became my everyday bottle

Became my everyday bottle.
Worth every £. Personally never write reviews but this bottle deserved one. Literally keeps ice drinks cold, i put ice in it and it lasts for over 6 hours before the ice melts. Use at the gym every day. Had this bottle for months now and still in perfect condition even after dumbells and weights have dropped on it. Perfect for deadlifts and hip thrusts. Best bottle possible.

Well worth the wait! Amazing quality and so durable. Really does make life a lot easier when lifting the waits off a must have if you're into the gym. An underrated item and I'd highly recommend it to all.

Super fast delivery. It's a super convenient tool for rapidly swapping plates during deadlift sets. Sets seem to take half the time.
Packaging is smart. The bottle itself is functional and brutalist. It's obviously quite big, but if you're the sort of gym goer who carries a protein shaker on the gym floor, you'll be right at home.

I never received my bottle

I never received my first bottle (Jan ‘23). Ordered November ‘22 and Karta kept the money for 2 months then randomly refunded me with no info on if/when it would be possible to get one.

Update March ‘24:
I finally got around to reordering, with the added bonus of the bottle now being available in a cute pink. I’m so pleased I came back to Karta after my original disappointing experience. I haven’t even tested it at the bar yet but love it already and can’t wait for deadlift day.

Hi Janine, thanks for taking the time to review your experience and we're sorry about the issues you had - we were hit with a supply chain delay at the start of this year and it didn't feel fair to keep customers' money during the period of uncertainty, so chose to refund all existing pre-orders.
The bottles are now back in stock so if you are still interested we'd love to have you back as a customer and will honour the original price you paid :) - Pete

Great concept

Great concept, great bottle my only issue with it is the lack of a carry strap. That’s all that’s stopping me from giving it a 5 star

I love the bottle

I love the bottle. Good quality, keeps my tea hot or my cold drinks ice cold and yes, does help a great deal with changing those weight plates. It came so well packed, you can see the care that went into the production of this. Will definitely get another one if there are different colours available.
